LOL, I love seeing my article(s) posted in discussion. But the theme industry is not going to last too long as the theme ecosystem is going to drastically change; especially if the core is considering a core-based theme where theme authors will apply CSS only.
As we end this year of 2019, I will be updating that article at Rough Pixels. For 2020, I will be looking to see how much of a ClassicPress market there is if I were to drop WP themes in the new year.
I won’t be submitting anymore themes to the WP theme directory either; the review queue is horrendous (currently a 4+ month wait time). A shame really because I liked submitting free WP themes to it, but with that wait time, it means I’d be lucky to only get 2-3 themes per year added there.
What I would like to see is a free CP theme directory at some point. I have some ideas on the process of it and reviewing themes.
